课堂中创设有效的教学情境,可以使抽象枯燥的数学知识变得生动。知识中融入情境,就像汤中溶入盐味道更鲜美一样,也会给课堂带来活力和美感。但是现在我们在听课、调研中发现,一些教师在创设情境时弄巧成拙,画虎不成反类犬,陷入情境创设的沼泽而不能自拔,影响了教学目标的实现。数学课堂教学究竟需要创设怎样的情境呢?我认为,创设有效的教学 Creating effective teaching situations in the classroom can make abstract and boring math a vivid one. Knowledge into the situation, just as the soup into the salt taste more delicious, will also bring vitality and beauty to the classroom. But now we are listening to lectures and research. We found out that some teachers are self-defeating when creating situations and are not the opposite. They fall into swamps created by situations and can not help themselves with the realization of teaching objectives. What kind of situations do we need to create in mathematics classroom? I think that to create effective teaching
